Use the data in the table below for the following 4 problems. For each, use the stated µ and σ to calculate the z score, get the p value (3 decimal places), and write out a formal APA statement of conclusion for each child. When you are finished with that, then answer the following question for each pair of parameters: Which child or children, if any, appeared to come from a significantly different population than the one used in the null hypothesis? What happens to the “significance” of each child’s data as the data are progressively more dispersed?

NOTE: Problems #1 and #2 are PRACTICE PROBLEMS with the answers available via the link beside them.

Problems #3 and #4 are GRADED PROBLEMS

Please submit all 4 problems using the Module 3 Assignment 1 Template found in the Doc Sharing area.

Problem 1. µ = 100 seconds and σ = 10 (practice problem 
Problem 2. µ = 100 seconds and σ = 20 (practice problem 

Problem 3. µ = 100 seconds and σ = 30 (graded problem)
Problem 4. µ = 100 seconds and σ = 40 (graded problem)

Given the research scenario, data points, set of population parameters and alpha set at p = .05, is the student able to generate the correct:

• Pair of hypotheses for each data point
• A z statistic and p value for each data point
• Decision about the null hypothesis for each data point
• APA-formatted statement of results for each data point

Please use Module 3 Assignment 1 Template located in Doc Sharing. Save the template so that you can make changes.

 

Please report z scores to two decimals and p values to three decimals. If the p value is less than .001, report it as p < .001.
